BURNER.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application led April 14, 1920. Serial No. 373,813.

To all whom t may concern.'

Be it known that I, Jos E. GONZLEZ, a citizen of the Republic of Cuba, and resident of Unin de Reyes, Province of Matanzas, Cuba, (whose post-Oiiice address is #15 Asuncin street Unin de Reyes, Province of Mantanzas, Cuba,) have invented certain new and useful Improvements in Burners, of which the following is a specication.

This invention relates to the combustion of liquid fuels in the boiler furnaces, and its object is to provide a burner for this kind of fuel, whose construction is very simple and most eiicient for pulverizing the fuel and spreading the same in films in a fan manner by means of a pressure Huid, whereby a thorough combustion of the fuel is obtained.

Another object of the invention is to provide a gas-burner of new construction wherein there are separate inlets for the steam and compressed air for the combustion and provides a previous heating of the fuel, as well as the mixture of the air with the previously heated fuel to be discharged in the combustion chamber.

In the annexed drawing illustrating the invention which will be hereinafter described:

Figure 1 is a side elevation of the burner.`

Fig. 2 is a plan View.

Fig. 3 is alongitudinal vertical section on line 3-3 of Fig. 2.

Fig. 4 Vis a longitudinal section on line 4 4 of Fig. 3.

Fig. 5 is a longitudinal section on line 5-5 of Fig. 3.

Fig. 6 is an elevation of the burner at the fuel outlet end, and

Fig. 7 is an elevation of the burner on the opposite end.

This burner comprises a prismatic box 1 whose interior is forming an upper chamber 2 and a lower chamber 3 separated through a horizontal division 3', and of which chambers the lower one 3 is of decreasing section in height and of increasing section in width, and inside the upper chamber 2, along three fourths of its length, and secured on its end to an opening of the inclined end wall of box 1 is extending a pipe 4 which has its two ends of widened section tapered toward the center or middle point, thus constituting a duct leading out of box 1.

Box 1 is provided at the inclined end engage end wall of wall wherein is secured pipe 4 and below the division 3, with a horizontal opening 5 of small height which constitutes a narrow outlet for the lower duct 3.

To said inclined end wall of box l is secured by means of screws 6 the plane cover 7 which presents a low cut 8 so that when the cover 7 is placed in position to box 1, the upper edge vof the cut may ush the upper edge of the opening 5 thus forming an outlet for the fuel in the fan manner shown in 10 in Fig. 5, to which effect the end edges 8 of said recess are beveled forming an extension of sides of duct 3.

The plane cover 7 has at its inner face and above the low cut 8 a recess or cavity'll of curved bottom which extends down in vertical direction as illustrated in 12 and terminates in inclined direction parallel to the face of cover 7 as shown in Fig. 3 forming a narrow duct 12 of increasing width which terminates above the opening 5.

From the upper portion of box 1 near its vertical end and at Yits longitudinal center upwardly projects a threaded mouth piece 13 to which is secured the threaded endof a pipe 14 through which is injected by pressure or gravity in the interior of chamber 2 the fuel to be used, which can be petroleum or a mixture of petroleum and molasses, and the pipe 14 is placed directly above the inlet of the inner pipe 4.

At the vertical end of box 1 on the same horizontal plane of pipe 4 and in alinement with the same, the box 1 presents a threaded hole wherein is secured the threaded end Of a pipe 15 which interiorly projects in front of inlet of pipe 4, and which pipe is designed to supply steam.

Box 1 is provided at its vertical end and parallel to the hole wherein is secured the pipe 15 and below division 3 another threaded hole wherein is secured by its threaded end the pipe 16 which serves as inlet for the compressed air to be supplied outfrom.

The operation of this burner is as follows: By discharging into chamber 2 through the pipe 14 the petroleum or mixture of petroleum and molasses, same falls therein vertically and on its fall is pushed out by the steam coming in horizontal line through pipe 15, and it is introduced through the widened open'end-of pipe 4, the fuel being outlet in the lower chamber,

thus heated and impulsed at higher pressure into the pipe 4 on passing through the reduced center thereof and coming out through the other widened end of pipe 4 to strike against the curved bottom of recess 11 of cover 7 and thence downward as indicated by the arrow; Vwhereupon the compressed air coming in through the pipe 16 into the chamber 3 and going out through the opening 5, owing to its great pressure, strikes against the fuel falling down'through duct 12 and spreads the same horizontally in a she-et as shown at 10 in Fig. 5.

ln this manner the combustion of the fuel is aided, as it is obvious that its combustion is thoroughly assured owing to the pulverization and mixture with the air inA the manner described after being previously heated by the steam.

It is obvious that the form of box and chambers can be varied without altering the spirit of the invention which is as pointed out in the appended claims.

ihat I claim is:

1. A burner for liquid fuel comprising ay box provided with two chambers, an upper and a lower one, and inside the upper chainber a pipe widened at its ends and reduced at its center leading from the interior chamber toward the exterior thereof, in combination with means for introducing the fuel in the upper chamber above the inlet of said pipe, means for introducing a hot fluid in the upper chamber in front of the inlet of said pipe., means for leading the mixture of fuel and hot fluid toward an introducing a pressure iiuid in the lower chamber.

2. A burner for liquid fuel, comprising a box provided with two inner chambers, an upper and a lower one, of which the upper chamber receives the fuel through a of the Y and means forV pipe with which the burner is provided at its top and said chamber also receives steam through a pipe secured through an end wall of the burner and projecting into the chamber on the the same horizontal plane of a pipe secured at the other opposite end wall of the burner and whose endsare widened and its center or middle point is reduced, this second pipeleading out to the exterior of the casing, and the other lower chamber is of decreasing width and provided with a pipe for inlet of the compressed air at its wider end and a horizontal outlet at its narrower end and means for leading the mixture of fuel and steam coming out from the upper chamber above the outlet of the lower chamber.

3. A burner for liquid fuel, which consists of a box provided with two chambers, an upper and a lower one. a plane inclined cover secured in a detachable manner to an inclined end wall of the box, the box being provided with an inlet for the fuel atl the top of the upper chamber, aV pipe ofV widened section at its ends and reduced at its center which terminates at one end beneath the inlet of the fuel and at the other end discharges into an opening of the inclined end wall of the box in front of the inclined cover thereof, a steam inlet in the upper chamber through its opposite end wallV and terminating in front of the inlet of the widened and reduced section pipe; the inclined cover presenting on its inner face andin front of the outer end of the same pipe a recess or cavity which extends downward and terminates above a lower recess in said cover in front of a horizontal outlet of the lower chamber, this chamber being tapered in width and height toward said outlet and an inlet for compressed air in the lower chamber.

ln witness whereof I affix my signature.
